“…For medium-voltage and high-power applications, low switching frequency techniques are preferred to minimize thermal stress on switches due to large switching losses [9], [10]. But low switching frequency produces output voltage or current of higher distortion [11]. Although low-pass filters can be used to dampen higher-order harmonics, pulse width modulation (PWM) approaches are limited in their ability to get rid of the more pervasive lower-order harmonics.…”

The use of multilevel inverters has gained popularity due to their ability to generate highquality output voltage with reduced harmonic distortion. The performance of these multilevel inverters can be improved by using a low switching frequency modulation scheme as it enables precise amplitude and harmonic control in the output voltage. Determination of optimum switching angles for minimum total harmonic distortion (THD) generally requires complex algorithms with large number of iterations. This work presents a novel approach for calculating optimum switching angles at low frequencies that produces low THD in the output voltage. The calculation process uses only one controlling parameter that allows easy computation of optimum switching angles with a lesser number of iterations. The effectiveness of the calculated switching angles in producing lower THD is verified through simulation in Matlab/Simulink platform as well as experimentally by developing a small-scale lab prototype of symmetric five-level inverter systems. For generalization, the proposed switching angle calculation technique is examined through different levels of inverter for minimum THDs. The superiority of the proposed switching technique is verified through an extensive comparison with other popular low-frequency strategies which revealed that the proposed technique produces lower THD and higher fundamental voltage than those of the Equal Phase (EP), Feed Forward (FF), and Half Height (HH) methods. This feature of producing higher-quality fundamental voltage would make it a preferred choice for high power multi-level inverters.INDEX TERMS Multilevel inverter, optimum switching angle calculation, total harmonic distortion, fundamental voltage, low frequency switching.

“…It is a voltage adjustment technique employed to regulate the voltage supplied to a motor. However, it is important to note that there is no universal PWM approach that can be universally applied to all applications due to their specific requirements and constraints [131]. Advancements in solid-state power electronics and microprocessors have led to the development of various pulse-width modulation (PWM) techniques for a wide range of industrial applications.…”

The state-of-the-art dynamic voltage restorers (DVRs) have advanced significantly in recent years. Modern DVRs can detect voltage sags or dips on the power line in real-time and are able to rapidly inject a compensating voltage to maintain a constant voltage at the load. This helps to improve the power quality of the electrical distribution system and to protect sensitive electronic equipment from voltage fluctuations. One key development in the field of DVRs has been the use of advanced control algorithms that enable the DVR to track the voltage more accurately on the power line and to inject a compensating voltage more accurately. These algorithms can be implemented using digital signal processors (DSPs) or field-programmable gate arrays (FPGAs), which allow for fast and precise control of the DVR. Another important development has been the use of high-frequency inverters in DVRs. These inverters can operate at much higher frequencies than traditional inverters, which allows them to switch on and off more quickly and to inject a more precise compensating voltage. This can help to further improve the power quality of the electrical distribution system. Overall, the state-of-the-art DVR technology continues to evolve, and new advances are being made all the time to improve the performance and reliability of these devices.

The world today is increasingly dependent directly or indirectly on the power system. Ensuring the quality of power supplied to electrical equipment is essential. The national regulatory framework is for harmonic mitigation in the global power system. This paper discusses the relationship between Efficiency (E), Security (S), and Reliability (R) for Electric Power Quality (EPQ). We measure the harmonic mitigation regulations listed in the IEEE 519 standard. To evaluate the proposed E, S, and R constructs and their relationship to EPQ, a multi-planning approach the method of Partial Least Squares-Structural Equation Modeling (PLS-SEM) and Deep Learning Artificial Neural Network (ANN) analysis were performed. In it, deep Learning Artificial Neural Network (ANN) was performed to complement the PLS-SEM findings and higher prediction accuracy. The study shows that the aspects of efficiency (E), security (S), and reliability (R) have a significant relationship with Electric Power Quality (EPQ). Another result of the study indicates that science, technology, engineering and math (STEM) resource conditions have a significant and positive impact on EPQ.
